Embodiment
Basic thought of the present invention is: for each locate mode among the GNSS is provided with new identification information, and notify or be configured in the user terminal, after determining the locate mode of user terminal, be carried in the GNSS id information identification information of locate mode and informing user terminal, user terminal positions according to the locate mode of being notified, and the present invention realizes simple and practical.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Embodiment one
Fig. 1 is the flow chart of the Notification Method embodiment one of locate mode in the long evolving system of the present invention, and as shown in Figure 1, the Notification Method of locate mode may further comprise the steps in the long evolving system of the present invention:
Step 101: when network side need obtain the position of certain UE, network entity SMLC sent location information requests to UE, sent measurement parameter that needs the UE measurement and the auxiliary data that needs UE to calculate simultaneously.
Step 102:SMLC determines that UE need use the locate mode of A-GNSS, needs so to indicate UE should use which kind of satellite system locate mode by auxiliary data, and specifically being provided with can be as follows:
Specific design is: an indication field is set in sending to the auxiliary data of UE, if lack the indication field of this setting in the auxiliary data, or this indication field is empty, and then expression indication UE adopts certain certain bits mode to position.As at newly-increased locate mode such as Galileo system location mode, then can adopt the mode in this example to notify locate mode, when set indication field was empty or does not exist, expression indication UE adopted the Galileo system to locate.And if the sign position that should be provided be empty, then notify UE to adopt which kind of satellite fix mode by following design, the corresponding relation of locate mode and identification information thereof is as shown in table 1 among the designed GNSS of this example:
Figure B2009100902245D0000041
Table 1
Last table only provides an example, and wherein each the satellite navigation system order in the table is not strict with, and other random orders can also be arranged.Just say that also for the various locate modes among the GNSS are provided with corresponding sign position, the notice by corresponding sign position realizes the concrete locate mode notice of (belonging to the locate mode among the GNSS) again.Also comprise WAAS (WAAS among the SBAS, Wide Area AugmentationSystem), European earth navigation overlapping service (EGNOS) synchronously, multisatellite enhanced system (MSAS, Multi-Functional Satellite Augmentation System) and auxiliary GEO (Geosynchronous Orbit) enhanced navigation poster presentation (GAGAN) system of GPS.Last with when increasing locate mode newly from now on, is used to indicate these newly-increased locate modes for keeping the position.
The locate mode that the situation of above-mentioned example is specially adapted in GNSS just is 2 nThe time, if increase a kind of locate mode this moment newly, if corresponding sign bit is set again for new locate mode, may need n indication bit expanded to n+1, this will cause very big system bearing expense, therefore, the indicating mode in this example can be adopted, the indication bit position of locate mode needn't be increased again.
Need to prove that SMLC is that UE determines that locate mode mainly is to determine according to the stationkeeping ability of UE and UE user's CAMEL-Subscription-Information.
After step 103:UE receives the auxiliary data of network transmission, position measurement or position calculation, determine the positional information of UE according to auxiliary data.
Embodiment two
Fig. 2 is the flow chart of the Notification Method embodiment two of locate mode in the long evolving system of the present invention, and as shown in Figure 2, the Notification Method of locate mode may further comprise the steps in the long evolving system of the present invention:
Step 201: when network side need obtain the position of certain UE, network entity SMLC sent location information requests to UE, sent measurement parameter that needs the UE measurement and the auxiliary data that needs UE to calculate simultaneously.
Step 202:SMLC determines that UE need use the locate mode of A-GNSS, needs so to indicate UE should use which kind of satellite system locate mode by auxiliary data, and specifically being provided with can be as follows:
This GNSS_ID project organization is considered and might network quality be caused loss of data, and if according to the indicating mode among the embodiment one, when the indication field in auxiliary data is lost, may make a kind of locate mode of selection of UE mistake.Therefore in this structure, do not design and lack or the branch process for empty the time.The corresponding relation of locate mode and identification information thereof is as shown in table 2 among the designed GNSS of this example:
Figure B2009100902245D0000061
Table 2
Last table only provides an example, and wherein each the satellite navigation system order in the table is not strict with, and other random orders can also be arranged.In the table 2,, the identification information of each locate mode among the GNSS in the table 2 is carried in the auxiliary data gets final product in the corresponding identification field for each locate mode among the GNSS is provided with corresponding identification information respectively.Implication every in the table 2 can be understood with reference to the associated description in the table 1, repeats no more here.
After step 203:UE receives the auxiliary data of network transmission, position measurement or position calculation, determine the positional information of UE according to auxiliary data.
